In master booster, green dragon is not so useful as its CC is too high. Conbra with its backstab is, in some ways, worse than reach. Glumbie,well…we can simply use demon dwarf to replace it.
How come the number of red is so many more than green and yellow? With relatively popular cards, they are red and purple, making the current situation with red-mono, purple-mono, red-purple as the main trend. Besides, it is possible to make 2 different mono-purple but it is hard to make other mono, such as green-mono and yellow-mono.
It is advisable to start thinking of making more epic allies other than red and purple cards at the same time, with usefulness.
